Abstract

 Meteorological data collected at mountain sites during the period 2006–2010 were archived under the Japanese Alps Inter-university Cooperative Project (JALPS). The site managers developed the data policy, and in situ data with metadata sets from 28 observation sites were prepared using a uniform format on a home page. Surface temperature lapse rates, including 3000-m level station data, agreed with previous results, in which the diurnal temperature range varied depending on location and season. A preliminary analysis comparing in situ and reanalysis data for temperature and wind speed showed a better agreement in terms of day-to-day variability but discrepancies in the diurnal mode. An evident weakening (warming) of daytime surface wind speed (temperature) was found at stations above the 3000-m level, indicating the development of convective layers. A new concept of data archiving using a super-site network within the framework of inter-university cooperation was proposed, and the importance of environmental monitoring by means of atmosphere-land interaction in mountainous areas was verified.
